`ErrorHandler` complicated all error handling in wabt, since it was
callback-based. Callbacks would be useful if we ever wanted to change
behavior when an error occurred, but instead all that the handler ever
did was write the errors to stdout/stderr or to a buffer.
This change adds a new class `Error`, which contains an `ErrorLevel`, a
`Location` and an error message. It also replaces ErrorHandler with
`Errors` (a typedef for `std::vector<Error>`), and adds a couple of
functions that can format a list of `Errors` for output:
`FormatErrorsTo{String,File}`.

Also remove wast-parser-lexer-shared.{cc,h}.

See issue 7037 in emscripten: the parsing of EXPORTED_FUNCTIONS as a
respones file doesn't work properly for the final element in the list.
Fixes issue #904.

It's not correct to use `--pre-js` and `--post-js` to wrap the module in
a function instance; instead we're supposed to use `-s MODULARIZE=1`.
This still keeps the build as (almost) asm.js, as switching to wasm is a
bit more work (we need to preload the wasm binary module).
This fixes issue #853.

`grow_memory` -> `memory.grow`
`current_memory` -> `memory.size`
This could have been a smaller change, but I took the opportunity to
rename the Token types, Expr types, and callback functions too. Many of
these are sorted alphabetically, so I resorted based on their new names.

libwabt.js was an old build with some fixed bugs (e.g. an infinite loop
in the parser).

Enabling this options allows better debugging in latest Firefox and Chrome.

Some minor redesign of demos.

Also change API to always work with modules, not scripts. This means
that many functions named `*wast*` are now called `*wat*`.
This also includes a bug fix in `wabt_write_binary_module`, where
previously the wrong buffer would be supplied to the `log_buffer`
result.

* wat2wasm only parses wat files (individual modules)
* wast2json parses spec test files and generates json + wasm

* Add demo index landing page
* Move old demo index -> wast2wasm/index.html
* Add demo for wasm2wast
* Fix bug when setting default values in JS:
`foo || true` will never be false, need to check for undefined
specifically.
* Fix bug in `allocateBuffer`; the offset in TypedArray.set is the
offset of the source buffer not the destination. You have to create a
new view to change the destination offset.
* Add new functionality to the emscripten build:
- Read binary file into `WasmModule`
- Converting from `WasmScript`/`WasmModule` to text or binary
* Wrap `libwabt.js` module in IIFE so as to not pollute the global
namespace with emscripten junk

This also includes a simple codemirror syntax highlighter for the wast
format, using the `simple-mode.js` codemirror plugin.
I've also moved the examples out from `demo.js` to `examples.js`.
The codemirror.css and codemirror.js files are marked as binary so they
don't show up in diffs; we shouldn't be patching them anyway.

* ast.{cc,h} => ir.{cc,h}
* binary-reader-ast.{cc,h} => binary-reader-ir.{cc,h}
* ast-writer.{cc,h} => wat-writer.{cc,h}
Everything else changes ast => wast.
When deciding between wast vs. wat, the wat format should only allow for
a single module, without assertions.

This removes the more complicated emscripten wrapper we used before, in
favor of something that is much simpler.
* Remove the memory init file
* Remove the onInputKey handling in the demo so it doesn't auto-indent
(it was broken now that we have the flat syntax)
* Simplify emscripten-helpers to provide very simple C-function wrappers
around the wast2wasm API:
* wabt_parse_ast
* wabt_resolve_names_script
* wabt_validate_script
* wabt_write_binary_module
The tricky part is that some functions return multiple values, so
those are returned as structs as well:
* WabtParseAstResult
* WabtWriteBinaryModuleResult

It complicates the code everywhere. It's faster to use a stack
allocator, but not worth the trouble for maintainability.

Also remove all the interpreter stuff. It's still in flux.

* renamed sexpr-wasm to wast2wasm
* renamed 'wasm-wast' binary to 'wasm2wast'
* added commands to generate symlinks to renamed targets
* fixed the issues causing the tests to break
* fixed a name error in travis-test script
* corrected repo name change int README
* renamed binaries in two tests and added a platform check in CMake for symlink generation for UNIX only
* reverted changes in test files due to breakage(for now)

This matches other files, and will be nicer if other lexers/parsers are
added. Also remove some references to flex, and the flex lexer.

* Need to call wasm.markUsedBlocks for the binary writer to work
properly
* Make .wast and .wasm into links
* Add another example, with a bunch of sections
* Clamp the length of the error caret line

The emscripten release build loads the module memory asynchronously,
which means you can't call any of the module functions until it has
loaded.
